Several parts that are easy to ignore when maintaining vehicles
Now, with the support of national policies, domestic cars have developed very fast, and many new brands and models have been developed, which easily dazzles car owners and makes them wonder which car to buy. Even if I buy it, because I am not particularly familiar with the car, I will only change the oil when I maintain it in the 4s shop. But in fact, there are thousands of parts in a car, and many parts actually need to be replaced, not just an oil.
For example, just like feeling hot in summer, car owners who often turn on the air conditioner should consider replacing the mechanical filter of the air conditioner. Therefore, in order to let car owners know something about the car, we will take stock of several parts that are easy to ignore when maintaining the car today. Can I just change the oil for car maintenance? All wet, these four parts are not maintained unless they are replaced.
The first one is a spark plug. Spark plug is an important part to start the vehicle, that is, the ignition device. Generally speaking, the service life of spark plugs is 30,000 km to 6,543.8+10,000 km, which means that spark plugs have a certain service life and cannot be used all the time as everyone thinks. However, this is only a rough figure, because the spark plug is made of different materials, so any value in this range may be scrapped, so everyone must check the spark plug carefully when maintaining it, and don't miss this noteworthy part.
The second is brake oil. Some people may not understand this. Because the car now is different from before, it uses hydraulic braking and needs braking to drive. However, because brake oil is easy to absorb water, we may find that there will be more water in brake oil after driving for a period of time, and the braking performance will be much worse after dilution, which will obviously decrease, so it is necessary to check and replace it regularly.
The third is the brake cylinder. This is a super easy-to-be-overlooked component, because of its location, it is mud, sand and water that it comes into contact with most often. So rust is inevitable. When the brake cylinder rusts, the wheels may lock. At this time, the fuel consumption will increase greatly because of the decrease of braking ability, so everyone must drive 20 thousand kilometers once, which is also for our driving safety.
The last one is the isotropic universal joint, and the nickname is "cage sleeve", which is a device to protect the cage. The material is rubber, which can play the role of dustproof and sealing. If the lubricating oil in the ball cage flows out, it will make the sound of the car abnormal or frustrated, which is very likely to cause traffic accidents. We must pay attention to it and replace it frequently.
